channel

This will be the name of the channel exactly as held by Postgres for sending
notifications. Internally this name will be truncated to the Postgres identifier

as a quoted identifier without unicode escape sequence support for use in
LISTEN/UNLISTEN commands. Examples of channel names and corresponding
NOTIFY commands:

when name == "the_channel": NOTIFY the_channel, 'msg',
NOTIFY The_Channel, 'msg', or NOTIFY "the_channel", 'msg'
succeed in delivering a message to the created channel

when name == "The_Channel": NOTIFY "The_Channel", 'msg',
succeeds in delivering a message to the created channel
